Remanufactured Transmissions for GMC Yukon

The GMC Yukon is built to handle everything from daily commutes to serious towing — but its transmission doesn’t always keep up. Whether you’re dealing with slipping gears, shudder under load, or pressure code faults, ACE offers a solution.

Our remanufactured transmissions are fully upgraded, dyno-tested, and ready to ship. Built with your shop in mind, each unit solves the real-world failures you see every week.

Common GMC Yukon Transmission Issues

  • Torque converter clutch (TCC) shudder and slip
  • Delayed or harsh 1–2 and 2–3 upshifts
  • Solenoid and valve body codes (P0894, P0776, P0741)
  • Overheating fluid in tow or fleet use
  • Internal clutch or sealing failures

These failures are frequent in Yukons using the 6L80, 8L90, and legacy 4L60E platforms.

Frequently Asked Questions (FAQ)

What are common transmission problems in the GMC Yukon?
Many GMC Yukon transmission problems stem from TCC slip, overheating, or solenoid failures. These are most frequent in 6L80 and 8L90 automatics around the 100K+ mile mark.

What’s the recommended Yukon transmission service interval?
For optimal reliability, shops should service the Yukon automatic transmission every 50,000 to 60,000 miles. This includes checking the transmission filter, inspecting fluid, and scanning for pressure or shift-related codes.

Should I flush the transmission fluid or just drain and refill?
If the transmission fluid isn’t burned or heavily contaminated, a standard transmission flush can help maintain smooth operation. Otherwise, a drain and refill with filter replacement is safer on older vehicles.

Do your remanufactured transmissions come with fluid included?
Yes. All of our remanufactured Yukon transmissions ship with Mobil 1 synthetic ATF — included in the box for convenience and performance.

How do I know if I need a full Yukon transmission replacement?
If your customer’s vehicle is showing repeat shift faults, metal in the pan, or multiple TCM-related codes, it’s often faster and more cost-effective to install a remanufactured unit than attempt partial repairs.
